Description Michael Forster CLA 2005-04-28 20:03:40 EDT 
The following code does not compile with the Eclipse Compiler (3.1M6 and
I20050426-1700), but it does with the Sun JDK Compiler (1.5.0_02).

----------------------------------------------------------------------

package bugreport;

import java.util.EnumSet;
import java.util.Set;

public class Bug<T>
{
    enum E { A, B }

    Set<E> set = EnumSet.of(E.A);
}

----------------------------------------------------------------------

The error message is:

    Type mismatch: cannot convert from EnumSet<Bug<T>.E> to Set<Bug.E>
Comment 1 Philipe Mulet CLA 2005-04-29 09:56:03 EDT 
Interestingly, removing the <T> parameter from type Bug makes the problem go away.
Comment 2 Philipe Mulet CLA 2005-04-29 11:53:19 EDT 
Added EnumTest#test102.

Several issues got surfaced. Lack of conversion to raw type for implict enum
references (through type of enum constant, or argument in supertype Enum<E>).
Also the qualified name E.A needed some intermediate raw conversion.

Fixed
